To @ZZ whom t may concern:

Be it known that I, JOHN G. KERST, a citizen of the United States,residing at Springfield, in the county of Sangamonv and State ofIllinois, have invented the new and useful Improvements in ShockingAccessories for IIarvesting-lVIachines, of which the following is aspecification.

My invention relates to shock-forming accessories for harvestingmachine`s,vand applies more particularly to a mechanism to beincorporated with a grain binder te coperate therewith for performingthe functions of cutting, binding ,and shocking ofthe grain.

The principal'object of the invention is to provide an automaticaccessory of the above character, which will receive the bundles ofgrain after they have been discharged from the usual binding mechanism,place them in an orderly manner in a grain shock, and later deliver thecompleted shock to the ground behind the moving machine.

A further object of my invention is to provide a` simple and reliablemeans for performing the several functions required of such a device,which may be readily adapted for use with the various designs of grainbinders, and which will prove efficient in operation, compact inconstruction, and inexpensive of manufacture.

' 1With the foregoing general purposes in view, .together with otherimportant specific objects to be hereinafter pointed out, my inventioncomprises the novel details of construction and arrangement, which willbe fully described herein, illustrated in the ac-4 companying drawings,and pointed out more specifically in the appended claims.

In the annexed drawings, wherein I have illustrated the preferredembodiment of my invention, like reference characters refer to like orcorresponding .parts throughout the several views. y v

Fig. 29 is a side elevationof the mechanism for actuating thelock pin for the gear shifting device.

The framework of my device, which may be of any suitable design, andwhich will be necessarily varied yby its application to various types ofharvester-s, has been designated in general by immoral 1. I havedesignated the harvester by numeral 2, only a portion ofthat frame beingdiagrammatically shown, the construction of devices of that characterbeing well known in the art, making it unnecessary to illustrate thatmachine in detail. The forward end of framework 1 is mounted upon axle3, the usual wheels 4 `being revoluble on the axle .on each side of theframework. rlhe method of mounting frame 1 to axle 3 shown very clearlyin Fig. 24, numeral 5 designating an upright bearing pedestal having alateral perforation in the lower end in which axle 3 is fixed, the upperend of the pedestal 5 being bifurcated to straddle the forward crossbeam of framework 1, a pivoting pin 5 passing through the bifurcatedupper end ofthe pedestal and through the cross beam atv right angles tothe axle. The flexible mounting thus provided obviates the difficultiesencountered by a rigid construction, when operating the device overrough and unevenl ground. Frame 1 is preferably attached to theharvester frame 2 by hinged joints, which are villustrated in Fig. 16.Bifurcated brackets 6 are attached to the harvester frame 2, and eyes 7are carried by framework 1, hinge pins 8 passing therethrough. The

'Opposite side of the frame 1 is supported by a castor wheel 9.

'l provide a bundle receiving trough 10, located on the frame 2 of theharvester at the point where the bundles are delivered from the binder.rlrough 10 comprises a bottom and side walls, the bundle being adaptedto lie longitudinally of the travel of the machine, with the butt-endforward.

The forward portion of the bottom of trough 10 is cut away, and a movinginclined conveyer belt 11 is carried in such eut-away portion, the beltbeing preferably elevated above the bottom of thetrough at the upperend.V Belt 11 is provided with cross slats and is 'trained over pulleys12 and 13, the upper pulley 12 being mounted on shaft 12, driven bysprocket wheel 14. Sprocket 14 is driven by chain 14 from sprocket 15 onshaft 16, which shaft is driven by means which will be hereinafter fullydescribed. The lower pulley 13, over which the belt-11v is trained beinglocated belowfpulley 12, and in a line considerably farther out from thepoint of delivering of the bundle, the butt of the grain bundle whenbrought into contact with the belt 11, will be engaged by the crossslats on the belt and drawn downward. The side wall of trough 10, isrounded at 10 allowing the bundle to be turned downward at the butt-Vend, and slightly outward toward the shocking device, the width betweenthe two Y side walls being predetermined. to allow isv 19, which bracketis suspended belo'w the harvester frame 2. As the bundle is drawndownward by belt 11, gravity will further actuate the bundle and it willfall butt-end downward onto receiving platform 17. Platform 17 willswing slightly downward about the pivoting point 20 in bracket 19, andthe rear end of arm 18 will be actuated upward. r1`he rear end of arm 18is curved upward and toward the harvester, where it is engaged with thegoverning mechanism having control of the bundle placing device. rIhismovement by arm 18 will set in motion the bundle placing device, theconstruction and operation of which will now be explained.

I provide a bevel gear 21 lixed to the main harvester axle 22, whichaxle is in contin uous rotation when the harvester is in operation. Atright angles to and meshing with gear 21, is a bevel gear 23 mounted onthe longitudinally disposed shaft 16. Shaft 16 is provided with a spurgear 24 adjacent the center of its length, and a disengaging ratchetclutch 2 5 rearward of gear 24, whereby a continuation shaft 16 may beengaged or disengaged. A second shaft, designated as 26 is mountedparallel to shaft 16, and a spur gear 27 is carried thereon. Gears 24and 27 being in mesh, the shaft 26 will be thus rotated by sh aft 1G.Shaft 26 comprises two sections, the rear section being designated bynumeral 26', a novel clutch means being provided for engaging anddisengaging the two sections. On the forward end of the rear section 26is fixed a circular head 28, provided on its forward face with a recess,on the outer circumference of which recess are ratchet teeth 28. Astationary head 29 is mounted to the frame 2 parallel to and spaced fromhead 28, and the rear end of the forward section 26 is adapted to rotatetherein. A ratchet gear 30 is fixed to the shaft 26 within the recess inhead 28, the ratchet being adapted to revolve within the recess.

Mounted to rotate in head 29. between the outer periphery of ratchet 30and the ratchet 28 is a catch 31, a pin 32 passing through aslidingarcuate bracket pivoting the catch. The pivoting pin 32 also pivots aweighted arm 34, the arm and catch being mounted to revolve in bracket33. Bracket 33 has an arcuate base, adapted to slide in an arcuaterecessed slot 33 provided in the rear face of stationary hea d 29,whereby the position of pin 32 and catch 31 may be shifted. Catch 31 isadapted, when the clutch is in its engaged position, to span betweenratchet teeth 2i and ratchet wheel 30, thus imparting the rotation ofratchet 30 and the forward end of shaft 26 to the head 28 and the rearsection 26 of shaft 26.

Parallel to and above the rear end of shaft Cyr 2G', is a governing drum35, wherein novel means are provided for actuating the bundle placingapparatus. Drum 1s mounted on shaft 50, driven from shaft 2G by bevelgears 46 and 49, through the medium of vertical shaft 51 having bevelgears L17 and 4-8 in mesh, respectively, with gears L16 and 49. Un theouter surface of drum 35, are cani grooves 36 and 36, which grooves areadapted to receive stub shafts 37 and 37, respectively. Groove 36T isadapted to actuate the movement of the bundle placing arm 3S, an uprightlever 40 pivoted at its lower end to the harvester frame to swing'forward and rearward at its upper end, being in fixed engagement withstub shaft 87', and the inotion of said lever being transmitted to link39, and through plvoted horizontal lever ft2, to the arm Groove 8G isadapted to actuate the movement of delivering arm a3, an upright leverl0 pivoted to the harvester frame to swing forward and rearward at itsupper end being' in liXed engagement with stub shaft 37, and the motionof said lever being transmitted to link 39 and through I bell-crank-l-fl, to arm 113. On the forward end of arm 38 is fixed a bundle basketl5, comprising a pair of superposed semi-circular arms. Basket l5 isslidably engaged on the back thereof to the bifurcated -forward end ofdelivering arm lf3, and the movement of arm 38 is such that the basketl5 will be moved substantially longitudinally on arm 43. Arm 13 swingsoutward across the shock forming platform about the pivoting point 51,whereby the grain bundle will be engaged by basket a5, and placed inposition on the shocking floor carried on framework 1;

lt will be understood that in forming the grain shock, it will benecessary to provide a plurality of different concerted movements forarms 4-3 and 38. 1n my present embodiment l prefer to form the shock ofseven bundles of grain, and sevenv different shockdelivering motions areperformed by the arms. Cam grooves 86 and 36 are formed suitably toactuate stub shafts 37 and 37 respectively, in order to accomplish thisa movement of the arms in an orderly and methodical manner.

The initial downward actuation of platform 17, caused by the deliverythereto of the first bundle of Orain to be placed in a L shock, willactuate the rear end of arm 18 forwardly about pivoting point 20 inbracket 19. A horizontal pin 52 is pivoted through the medium of abell-crank 18 to the upper end of the curved rear end of arm 18 the rearend of which pin is normally inserted in a hele 52 therefor throughstationary head 29 of the clutch mechanism on shaft 26. Pin is normallyheld in position protruding into the upper end of arcuate slot 53. Slot53 is adapted to receive a stub pin 55 carried by weighted lever 3st,and to allow the pin to travel therein, and the function performed bythe end of pin 52 is to prevent the travel of the stub pin by protrudinginto the path thereof. 1t will therefore be seen that when pin 52 isdrawn forward out of the path of travel of stub pin 55, the stub pin andweighted arm 3e will be free to swing upward about pivoting point 32.Normally catch 31 is out of engagement between ratchet 30 and theratchet teeth 2S in head 28, pin 52 preventing engagement, but uponremoval of pin 52, and upon the upward movement of the inner end of arm34, catch 31 will be swung slightly with the arm about pivoting point32, and will form an ope 'ative engagement between the continuouslyrevolving ratchet 30 and the ratchet teeth 28. Rotation will thus betransmitted to the rear section 2G of shaft 26, and to the drum 35,whereupon the first bundle of grain will be delivered to its position onthe shocking floor, and the arms'returned to their normal position. Artthis point stub pin 55 will have been actuated along the outer side ofarcuate groove 5.3 in head 29 by catch 31 and ratchet 30, bracket 83being also moved around in its arcuate slot 38', when the stub shaft 55will encounter a slight variation from the arc, adapted to force the pininward adjacent the lower end of the slot. The protruding end of aspring actuated pin 56 will be encountered, the stub shaft 55 engagingthe pin and pushing it out of the path of travel against the oppositeactuation of its spring. Stub pin 55 will travel to the lower end of theslot 53, whereupon the spring will force the pin 5G to its normalprotruding position to prevent access to the outer side of slot 53. Pin55 may then travel unimpeded upward along the inner side of the slot,the weight on the arm actuating such movement, a partition lin 511 beingpositioned centrally of the slot to confine the stub pin 55 to tra-velin the desired path. At the end of the travel upward, further movenientin the slot will be prevented by pin 52, which will have been returnedto its normal position by spring 53.

The remaining different movements will be similar to the motion justdescribed, and it is not thought necessary to describe them in detail.Cam grooves 86 and 3G will effect the necessary movements of arms 43 and38, when each succeeding movement is initiated by the falling of asucceeding bundle of grain on the platform 17, and the consequentwithdrawal of pin 52 from engagement with stub pin ylhe grain bundlesare positioned on the shocking floor directly within parallelsuper-posed shock-receiving yokes designated by numeral 57, of whichthere are four sets equally spaced. about a central turret 58. Yokes 57are semieircular in shape-and are adapted to embrace the shock, a hingedeX- tension arm 59 being pivoted to the forward end of each yoke tofurther embrace the shock after it is formed. Turret 58 and yokes 57 arerevoluble about a central post 60, the shock when formed being revolvedone-quarter of a revolution thereby to a position directly rearward ofthe post 60. Another set of yokes will be simultaneously revolved to thereceiving position. The revolution o f turret 58 is eected by the crankarm 61 carried by the ratchet 62 on the upper end of the turret, a reachrod 63 being pivoted to the crank arm 61, and extended diagonally acossthe machine to horizontal crank disk 64 rotated by shaft 16 throughbevel gears 65 and 66 and upright shaft 67, gear 65 being fixed to shaft16, and gear 66 being fixed to the lower end of shaft 67, to

which the crank disk 64 is attached. Movement of arm 61 being thuseffected, clutch 62, which is adapted to engage turret 58 duringclockwise movement of the clutch, will draw turret 58 around in thatdirection. Clutclr- 62 is provided with a circular inside bearing aboutthe turret, ratchet teeth 58 being provided on the outer periphery ofthe turret.k A spring actuated pin 68 is carried on the arm 61, and isadapted to normally protrude against the turret. rIeeth 58 will engagesaid pin, thus engaging the clutch ring 62 in operative relation to theturret. When reach rod 68 has been drawn to the limit of its rearwardtravel by crank disk 64, it will be reversed by the further rotation ofthe disk, and will travel forward.

i Arm 61 and clutchv ring 62 will thereby be reversed .to travelVcounter-clockwise, and such motion will not be transferred to theturret, since the ratchet teeth are tapered in the opposite direction.The counter-clockwise movement of the clutch is only for sufficientdistance to allow the neXt ratchet tooth on the turret to kengage pin68.

At the point in the clockwise rotation of turret 58, when the arm 61 hasmoved the `turret to the limit of travel of that arm,

K. posed a coil spring, adapted to normally force pin 72 downwardthrough lower lug 71 into engagementwith'the upper horizontal face ofturret 58. A series of four spaced apart holes 72 are provided in theupper face ofthe turret in position to register with and receive the pinat the predetermined points marking the limit of travel desired for theturret, which is shown as one-quarter of the complete revolution of theturret.

Pin 72 will thus lock the turret in position during thecounter-clockwise movement of clutch 62. In order to raise pin 72 fromengagement with one of the holes 72', I provide a wedge shapedprojection 78 on the upper face of clutch 62, adapted to engage apivoted block 74 carried parallel to and slightly farther out from itscenter of rotation than pin 72. Block 74 will normally travel just abovethe face of the clutch, and when wedge 73 is encountered,l the blockwill be raised thereby, the block in turn raising pin 72 from the hole72', thus unlocking the engagement between the lock pin 72 and theturret. In order to accomplish the foregoing unlocking operation, Iprefer to provide considerable over-travel for the ratchet ring, whichwill allow the wedge to raise pin 72 completely out of hole 7 2, beforethe ratchet will be engaged by pin 68.

A simple and effective device is provided for opening and closing theextensions 59 carried by the upper shock receiving yoke 57, it beingunderstood that such extension arms are preferably normally closed,except during that portion of the revolution when the turret'isstationary to receive a shock or to discharge the same. Arms 59 of whichthere are four are each provided on their pivoted ends with a bell-cranklever 80, a horizontal link 79 extending inward therefrom to the upperend of a vertical lever 77. Levers 77 are each fulcrumcd adjacent thecenter of their lengths by means of pivoting pins passing through lugs78 on the turret. Levers 77 together with the arms and links travel withthe turret about central post 60, which post is anchored in bearingplate 75 supported by the framework 1. The upper face of plate 75 isprovided with cam groove 76 in which the lower free ends of levers 77are adapted to travel. When one set of the receiving yokes 57 has beenrotated to the point just prior to reaching the position to receive thebundles of grain from the platform 17, a variation in groove 76 isreached by the corresponding lever 77, and the lever will be actuatedoutward at the bottom, thus drawing link 79 inward and actuatingbellcrank S0 to throw the free end of arm 59 outward. At this point theturret will have reached its position of rest. Upon the completion ofthe shock, and upon the initial movement of the turret in transferringthe shock, lever 77 will be thrown inward at its lower end, thusswinging arm 59 inward about the shock, where it will remain until thelever is actuated by another variation, which isA positioned to operateupon the shock being delivered to the discharging device. Y After theshock has been discharged, and upon rotation of the turret thereafter,the arm will be returned to its closed position and remain closed untilagain actuated by the mechanism just described.

In order to prevent tilting of the shock in the direction of the openingbetween the ends of yoke 57 and arm 59, during the travel from theshocking floor to the discharging position, l provide a guard rail 81,attached to framework 1 just rearward of the shocking floor, the guardbeing curved to conform to the travel of the shock about post 60.

Upon the delivery of the grain shock to the discharge position directlyrearward of turret post 60, a means for discharging the shock upon theground is automatically brought into play. A longitudinally slidablefloor 82 is provided just rearward of post 60, to receive the shock fromthe stationary shocking floor, slidable floor 82 being mounted to shiftin guide irons 83 suspended below frame 1, and disposed with the rearends ust above the ground and the forward ends considerably higher,providing an inclined slideway for floor 82. rlhe forward edge of floor82 is fixed to a longitudinally extending actuating arm'8l provided witha gear rack on its upper face,

which rack is in mesh with actuating gear 85 suspended from theframework 1. Gear 85 is actuated from aXle 22, through the medium ofeither set of two chains of gears, one chain providing rearwardactuation of rack 84, and the other chain providing forward actuationthereof.

The method of actuating gear rack 84 has been previously disclosed in aformer application for Letters Patent, bearing Serial No. 77 8,1113,filed dune 10, 1913, but important improvements are new incorporatedtherewith, in the method of automatically shifting the gears, and it isthought necessary to briefly describe the operation of the drivingdevice in order to more clearly disclose the new features.

Numeral 86 designates the lateral drive shaft mounted to bearings inframe 1, a sprocket gear 87 being attached to the harvester end of theshaft, which sprocket is driven by a chain 88 from sprocket gear 89fixed to rotate with axle 22 of the harvester. @n the opposite end ofshaft 86 is fixed a spur gear 90 in mesh with a second spur gear 91carried by shaft 92. Shaft 92 is parallel to shaft 86, and is mounted torotate in bearings in frame 1. A. third lateral shaft 98 is disposedbetween and below shafts 86 and 92, and gears 85 and 94; are fixed.thereto, gear 85 being in mesh with rack $4-, and gear 94C positioned tobe driven, selectively, by gears 95 and 96, mounted to rotate withshafts 86 and 92, respectively. Gears 95 and 96 are mounted to slidelaterally into and out of mesh with gear 94, a lever 102 therefor beingprovided, and automatic means incorporated therewith for operating thesame. lt will be seen that upon the forward movement of the harvester,aXle 22 will drive shaft 86 in a counterclockwise direction as viewed inF ig. 4r, and that gear 90 will drive gear 91 and shaft 92, in aclockwise direction. Upon the meshing of gear 95 on shaft 86 with gear94 on shaft 93, gear 85 will be rotated in a clockwise direction, thusactuating gear rack 841 and platform 82 forward. Upon the meshing ofgear 96 with gear 941, the opposite direction of travel will be impartedto platform 82. Gear 94 is provided with a blank p0rtion 9-1/ in itsperiphery, in order to insure a limited movement in either direction..lhen the driving gear reaches that blank portion, further movement ofthe platform will cease.

The automatic means for shifting the gears 95 and 96, at the properpoint in the operation of the entire device, will now be described, itbeing understood that it is the purpose of such mechanism to withdrawthe floor 82 from beneath the shock, when the shock is rotated by turret58 to the floor 82.

0n shaft 16, just rearward of clutch 25, is a cam 106 adapted to berotated by that shaft, and provided with a cam groove in operativerelation to a stub pin carried by a crank arm105. Crank arm 105 is keyedto an oscillating longitudinal shaft 98, on the forward end of which isa relatively short vertical crank arm 99. To the outer end of arm 99 ispivoted a connecting rod 100 extended laterally across the interveningspace to pivotally engage the E -shaped arm 101 of the gear shiftinglever 102. Lever 102 is fulcrumed between shafts 86 and 92, and each endthereof is pivoted to collars carried by the sliding gears96 and 95,respectively. It will beseen that lateral movement of connecting rod 100will actuate lever 102, to throw gears 95 and 96 selectively, into meshwith gear 94:. Rod 100 is preferably longer than required, that is it isallowed to extend through arm 101 a short distance, in order to provideover travel to insure flexibility of the entire machine when inoperation on uneven ground. A coil spring 10-1 carried about shaft 92 isdisposed between a stationary bearing 92 and a loosely fittingcollarv103 carried by shaft 92, the collar being positioned underL-shaped arm 101 and pivoted thereto by a pin in the collar protrudingupward into a longitudinal slot in arm 101. It will be seen that thespring 104 will normally actuate arm 101 to draw connecting rod 100toward the driving mechanism, thus providing the desired tension toinsure accuracy of operation of the shifting device.

ln order to lock arm 101 in position, I provide a lock pin 1116,positioned to be raised to engage the arm when the arm is moved to itseXtreme travel toward the harvester. Pin 146 is pivoted to a crank arm140 fixed to lateral shaft 141, on the outer end of which is Va downwardextending crank arm 142. A link 143 is pivoted to the lower end of arm142, and to the upper end of a lever 144. Lever 144 is fulcrumedadjacent its center to the shocker frame, and the lower end of the leveris free, being positioned to be engaged by a lug 84, carriedon the sideof actuating arm 84 of the platform. When the platform has been drawnfoiuvardV to a. predetermined point, lug 84 will actuate lever 144, andthe pin 146 will be drawn down to disengage arm 101, allowing theshifting device to operate.

This operation is primarily initiated by the engagement of clutch 25,thus throwing into rotation shaft 16, the forward section 16 being incontinuous rotation. rlhis engagement is effected by the mechanism shownin Fig. 18, a tooth 110 being positioned on the periphery of revolvinghead 28 on shaft 26, which tooth is tapered to force the free end of aclutchshifting lever 111 slightly forward about pivoting point 111,thereby throwing the sliding collar attached to the forward head ofclutch 25, into engagement with the rear head. TheV adjacent faces ofthe-clutch heads are preferably toothed to mutuallyy engage, a spring112 being counter-sunk into the adjacent faces to normally preventengagement. Upon the movement of lever 111 by lug 110 slightly forwardat its free'end, pin 113, normally prevented from upward movement byengagement on the under side of lever 111, will be free to be actuatedupward by spring 114, thus to hold lever 111 and the rear head of clutch25 in engagement. At the predetermined point when the rotation of shaft16 is no longer required, a tooth 25 on the periphery7 of the rear headof clutchl 25 is positioned to engage a lever 107 fixed to rotate shaft108, and thereby crank arm Arm 109 is in operative engagement with thelower end of pin 113, and adapted to draw the pin downward, therebyallowing lever 11.1 to swing back to its normal position, actuated bythespring 112.

During the operation of forming the shock, a means is provided forsteadying the bundles; A. hand 115 comprising a plurality of horizontalfingers is mounted to a stationary collar 116 fixed to post 60 and Yadapted to be suspended over the shocking floor just high enoughthereabove to slightly engage the bundle heads where the shock is beingformed. Collar 116 comprises a fulcrum 116, to which is pivoted the hand115, a. bell-crank 115 on the inner side of the hand being pivoted to alink V117. Link 117 is engaged by a pivoted lever 118, to which anactuating reach rod 119 is pivoted. Rod

,119 is actuated back and forth by a longitudinal oscillating shaft 120,carrying a vertical crank arm 121 on its forward end, the

f rear end of the shaft being provided with an arm 122, engaged inoperative relation with a cam groove on the rear face of cam 123 rotatedby shaft 16.

In order to support the grain shock when the sliding discharge floor isbeing withdrawn from beneath the shock, I provide corner posts 124 fixedto the framework 1 at each of the rear corners, about each of whichposts rotating sleeve 125 is disposed. A coil spring 126 is carriedabout the sleeve, the upper end thereof being engaged to a stationaryarm. 128 provided on the post. The lower end of the spring is engaged toan arm 127 carried on the lower end of sleeve 125, the arm and sleevebeing thus normally actuated about the post by the spring. The shocksupporting arm 130 is fixed to the upper end of sleeve 125 and isadapted to normally extend inward from the post across the rear end ofthe accessory, an extension arm 131 being pivoted thereto at point 132.A link 129 is pivoted on one end to a bell-crank extension on thepivoted end of arm 131, the link being pivoted on its other end to thestationary arm 128. The arm 127 onlthe lower end of sleeve 125 isnormally positioned to engage a catch 136 pivoted to the framework 1,thus to allow the arms 130 and 131 to extend across the rear edge of thedischarging fioor, but upon the forward movement of that floor, a lug137 carried by the floor will engage and actuate the catch out oflocking relation to arm 127. Thesupporting arm will then be free toswing against the shock, actuated by spring 126. The tension of thespring is preferably only sufficient to allow the arms to rest lightlyagainst the shock, and to give as the machine advances, stationary arm128 drawing the bell crank end of arm 131 about pivoting point 132,through the medium of link 129. This affords a flexible support,allowing the shock to be deposited upon the ground without the bundlesbeing scattered from their shocked relation.

lhcn the major portion of the shock has been deposited on the ground,that is, when the discharging floor has been drawn from beneath thegreater part of the shock, -I provide an automatic means for withdrawingthe supporting arms from engagement with the shock. This means comprisesa longitudinally extending reach rod 133 pivoted to arm 132 on each ofthe sleeves 125, the rear end of the rod being bent inward at rightangles to the guide irons of the framework, and entered into alongitudinal guide slot 134 provided therefor. The bent end of rod 133is designated as 133, and a catch. 135 is pivoted to travel with floor82 and to engage the rod at a predetermined point. The rod will therebybe moved along slot 134, and the sleeve 125 and arms 130 and 131 will beswung out of engagement with the shock. To release the engagementbetween catch 135 and rod 133', a wedge shaped extension is provided oncatch 135 adapted to engage with a stationary abutment 138 on the frame.As the extension is forced beneath the abutment by the movement of thefloor, the catch will be swung down disengaging rod 133. When the floorreturns to its shock receiving position, lug 137 will engage latch 36,and sleeve 125 and arms 130 and 131 will be thrown around by spring 126to their normal position.
